Adamant Custom 24-Core i9-14900K RTX 5090 32GB DDR5 2TB NVMe gaming PC

System Overview

This Adamant Custom desktop arrives as a complete Windows 11 Pro workstation built around a 24-core Intel Core i9-14900K processor and an Nvidia GeForce RTX 5090 graphics card with 32GB of video memory. The platform targets creators and enthusiasts who need strong multi-threaded compute and high-end GPU acceleration in a single pre-assembled chassis.

Build and Connectivity

A 360mm liquid cooler handles the CPU while the Antec P20 mid-tower supplies three front 120mm fans, dust filters on three faces and tempered-glass side panels. The front panel offers two USB 3.0 ports, one USB 3.2 Gen 2 Type-C connector and audio jacks; the rear I/O adds two USB Type-C, two USB 3.2 Gen 2, four USB 3.2 Gen 1, Intel 2.5Gb Ethernet, Wi-Fi 6 and BLUETOOTH 5.2. Internal bays include two 3.5/2.5-inch and two dedicated 2.5-inch slots, while the Z790 TUF motherboard provides four M.2 sockets and four SATA 6Gb/s ports for further expansion.

Platform Limits

The CPU tops out at 6.00 GHz with 36 MB of L3 cache and supports up to 192 GB of DDR5 across four slots, though only 32 GB is installed. The Samsung 990 PRO 2TB NVMe drive delivers sequential reads up to 7450 MB/s and writes up to 6900 MB/s over a PCIe 4.0 x4 link. The 1200W 80 PLUS Gold power supply uses a 140mm fan and Japanese main capacitors, while the case measures 469 x 220 x 490 mm, restricting oversized components that exceed those clearances.
